Precautions for wiring
The following precautions must be taken when wiring the Analog Input Module.
1. The module must be kept away from the alternating current (A/C) wire to avoid
surge or inductive noise produced from the A/C supply wire.
2. Select the cable considering the ambient temperature and value of the current. The
maximum size of the cable must not be less than the standard cable size of AWG22
(0.3mm²).
3. The cable must not be too close to a hot device/material and in direct contact with
oil for a long period, as it can result in damage or abnormal operation due to short-
circuit.
4. The polarity check must be performed before wiring.
